Description

Lifting gantry frame Technical Field

[0001] This utility model relates to the field of gas turbine hoisting tools, specifically a hoisting gantry frame. Background Technology

[0002] Gas turbines have a wide range of applications and a significant position in national defense and the national economy. They are the highest-end products in the energy and power equipment field, representing the highest technological level of the equipment manufacturing industry. As the name suggests, aero-engine-derived gas turbines are gas turbines modified from aero engines. Aero-engine gas turbines exhibit diversified and serialized development characteristics. In terms of diversification, different types and levels of gas turbines can be developed based on the same aircraft. Influenced by military and economic factors, the development of aero-engine technology is faster than that of gas turbines. Gas turbines and aero-engines share a wide range of technological commonalities, and can share and utilize design systems, manufacturing systems, talent systems, and testing systems. Therefore, based on the huge market demand and obvious application advantages of gas turbines, developing gas turbines by relying on high-performance, mature aero-engines and advanced industrial technologies and design methods has become an industry consensus. There are two ways to transfer aero-engine technology to gas turbines: one is to directly modify and derive mature aero-engines to form aero-derived gas turbines; the other is to transplant aero-engine technology to heavy-duty gas turbines, researching and developing a new generation of heavy-duty gas turbines.

[0003] Gantry cranes are a new type of small lifting gantry crane developed to meet the daily production needs of factories for moving equipment, loading and unloading goods in and out of warehouses, lifting and repairing heavy equipment, and transporting materials. They are suitable for mold manufacturing, auto repair shops, mines, civil construction sites, and other applications requiring lifting capabilities. Commonly used in construction, they serve as both material transport and a means of transporting construction workers, achieving mechanized lifting. This reduces manpower, lowers production and operating costs, and improves work efficiency.

[0004] Gantry cranes are used either inside factories or outdoors, but they have many shortcomings in connecting the two. Specifically, the entrances and exits of factories are not large, and existing gantry cranes cannot be used for large equipment when it is entering or leaving the factory, especially when the doors are not high. In this case, it is very troublesome to move large equipment from the outside to the inside or from the inside to the outside.

[0005] Gas turbines derived from aero-engines are installed inside the generator set. However, the space inside the generator set is limited. When it is necessary to remove the turbine and ship it back to the manufacturer for maintenance, it is impossible to remove the turbine from the generator set using a gantry crane, nor is it possible to install the generator set from the outside into the generator set. Therefore, a new type of hoisting structure is needed to solve the existing problems. Summary of the Invention

[0006] The purpose of this invention is to solve the problem that existing hoisting tools are not suitable for hoisting gas turbines in power units, and to provide a new hoisting tool that can be used for hoisting operations from indoors to outdoors in situations with small entrances and exits.

[0007] To solve the above-mentioned technical problems, the present invention provides a lifting gantry frame, including a first support beam and a second support beam. The first support beam is at a horizontal angle, the second support beam is at a higher horizontal position than the first support beam, and one end of the second support beam is fixedly connected to the middle of the first support beam.

[0008] The first support beam has fixedly connected support rods at both ends below it;

[0009] Each of the support rods has a fixedly connected extension rod at its vertical lower part;

[0010] The other end of the second support beam has a fixedly connected connecting seat, and the connecting seat has a limiting groove that runs through both ends of the connecting seat; the front and rear sides of the connecting seat each have at least two positioning holes, and the at least two positioning holes are located at different heights.

[0011] It includes a positioning element that passes through any one of the positioning holes of different heights, and the end of the positioning element is at least partially located within the limiting slot.

[0012] In a preferred embodiment of the lifting gantry frame of this utility model, each of the support rods has a first connecting plate fixedly connected to its upper and lower ends;

[0013] The extension rod has a second connecting plate fixedly connected to its upper and lower ends; the first connecting plate at the upper end of the first support beam is fixedly connected to the first support beam; and the first connecting plate at the lower end of the first support beam is fixedly connected to the second connecting plate at the upper end of the extension rod.

[0014] As a preferred embodiment of the lifting gantry frame of this utility model, the two ends of the first support beam are respectively fixedly connected with first mounting sleeves;

[0015] The upper end of the support rod has a first support sleeve rod that is fixedly connected, and the first support sleeve rod is installed inside the first mounting sleeve.

[0016] In a preferred embodiment of the lifting gantry frame of this utility model, the middle part of the first support beam has a fixedly connected second mounting sleeve; the lower part of the end of the second support beam has a fixedly connected second support rod, and the second support rod is installed inside the second mounting sleeve.

[0017] In a preferred embodiment of the lifting gantry frame of this utility model, the upper surface of the second support beam has a fixed ring for fixed connection.

[0018] In a preferred embodiment of the lifting gantry frame of this utility model, the lower part of the connecting seat has a fixedly connected clearance position, and the second support beam is at least partially located within the clearance position.

[0019] As a preferred embodiment of the lifting gantry frame of this utility model, it includes a support block, and the positioning member is detachably connected to the support block.

[0020] Beneficial effects

[0021] This utility model solves the above-mentioned existing problems and other existing problems not mentioned above, and brings at least the following innovative advantages:

[0022] This utility model relates to a lifting gantry frame. The extension rods on the support rods can increase the height, and different lengths of extension rods can be used to flexibly adjust the height. The connecting seat on the second support beam can be used to connect with the crossbeam inside the unit or indoors. This allows the connecting seat to connect with the crossbeam inside the unit, while the support rod is located outdoors, forming a sliding beam extending from indoors to outdoors. A hoist or pulley can be installed on the second support beam, enabling convenient hoisting of gas turbines or other large equipment from indoors to outdoors. The connecting seat has positioning holes at different heights, allowing positioning components to be installed at different heights.

[0023] This utility model of a lifting gantry frame further enhances overall stability by adding a first mounting sleeve, a first support rod, a second mounting sleeve, and a second support rod between the first and second support beams. Furthermore, the inclusion of the second mounting sleeve and the second support rod allows the first support beam to be at least partially adjusted in angle around the second support rod as an axis, after the second support beam is fixedly connected to the unit or interior space.

[0024] The lifting gantry frame of this utility model, through the setting of the clearance position, makes it easier to install the hoist or pulley assembly on the second support beam.

[0025] This utility model of a lifting gantry frame, through the setting of support blocks, allows the combination of support blocks, positioning components, and multiple positioning holes of different heights to achieve different bottom positions of the positioning components, thereby achieving better matching with the height of the gas turbine unit or the indoor beams.

One end of the second support beam 2 is fixedly connected to the middle of the first support beam 1.

[0034] As shown in Figure 1, the first support beam 1 has support rods 3 fixedly connected to the bottom of both ends; and each support rod 3 has an extension rod 4 fixedly connected to the bottom of its vertical direction.

[0035] As shown in Figure 1, the other end of the second support beam 2 has a fixedly connected connecting seat 5. Figure 3 shows that the connecting seat 5 has a limiting groove 6 that runs through both ends of the connecting seat 5. The connecting seat 5 has at least two positioning holes 7 on its front and rear sides, and the at least two positioning holes 7 are located at different heights.

[0036] Including the positioning element 8, Figure 3 shows that the positioning element 8 passes through any one of the positioning holes 7 at different heights, and the end of the positioning element 8 is at least partially within the limiting slot 6.

[0037] This utility model relates to a lifting gantry frame. The extension rod 4 of the support rod 3 serves to increase its height, and different lengths of extension rod 4 can be used to flexibly adjust the height. The connecting seat 5 of the second support beam 2 can be used to connect with the crossbeam inside the unit or indoors. This allows the connecting seat 5 to connect with the crossbeam inside the unit, while the support rod 3 is located outdoors, forming a sliding beam extending from indoors to outdoors. A hoist or pulley can be installed on the second support beam 2, facilitating the lifting of gas turbines or other large equipment from indoors to outdoors. The connecting seat 5 has positioning holes 7 at different heights, allowing the positioning element 8 to be installed within these holes.

[0038] As shown in Figure 2, each of the support rods 3 has a first connecting plate 9 fixedly connected to its upper and lower ends; and each of the extension rods 4 has a second connecting plate 10 fixedly connected to its upper and lower ends. As shown in Figure 1, the first connecting plate 9 at the upper end of the first support beam 1 is fixedly connected to the first support beam 1; the first connecting plate 9 at the lower end of the first support beam 1 is fixedly connected to the second connecting plate 10 at the upper end of the extension rod 4. As shown in Figures 1 and 2, each of the two ends of the first support beam 1 has a first mounting sleeve 11 fixedly connected; the upper end of the support rod 3 has a first support sleeve 12 fixedly connected, and the first support sleeve 12 is installed inside the first mounting sleeve 11. As shown in Figures 1 and 2, the middle part of the first support beam 1 has a second mounting sleeve 13 fixedly connected; the lower end of the second support beam 2 has a second support sleeve 14 fixedly connected, and the second support sleeve 14 is installed inside the second mounting sleeve 13. This utility model of a lifting gantry frame further enhances overall stability by adding a first mounting sleeve 11, a first support rod 12, a second mounting sleeve 13, and a second support rod 14 between the first support beam 1 and the second support beam 2. Furthermore, the installation of the second mounting sleeve 13 and the second support rod 14 allows the first support beam 1 to be at least partially adjusted in angle around the second support rod 14 as needed after the second support beam 2 is fixedly connected to the unit or indoors.

[0039] As shown in Figure 1, the upper surface of the second support beam 2 has a fixedly connected retaining ring 15. Figure 3 shows a fixedly connected clearance position 16 below the connecting seat 5, within which the second support beam 2 is at least partially located.
